An Idaho Republican state lawmaker who was under investigation for possible sexual abuse, died in an apparent suicide on Tuesday, according to authorities.

Canyon County Coroner Vicki DeGeus-Morris said Brandon Hixon was found dead of a self-inflicted gunshot wound to the head in his Caldwell home early Tuesday morning. A family member discovered his remains.

Hixon, 36, was elected to the Idaho Legislature in 2012. At the time, Hixon was one of the youngest lawmakers elected to the Idaho House of Representatives.
